Is Jeremiah LGBTQ?
Jeremiah’s sexuality is explicitly confirmed in the books but remains unlabeled on screen — a gap that leaves the TV character in a different space than his literary counterpart.
One of the most searched questions about Jeremiah Fisher is whether he is LGBTQ — and the answer depends entirely on which version of the story you’re reading. In the book trilogy by Jenny Han (Penguin New Zealand), Jeremiah is confirmed as bisexual. The Wherever I Look cast guide describes him as “equal opportunity” and notes that he boasts about kissing boys and girls. The guide also calls out his playful dynamic with Steven as contributing to his queer-coded social presentation.
Did Jeremiah date a guy?
- In the books, Jeremiah has relationships with both boys and girls. The character guide (Wherever I Look) explicitly mentions Jeremiah kissing boys.
- The TV series has not shown Jeremiah dating a guy as of the end of Season 2.
Is Jeremiah bisexual in the books?
- Yes — multiple sources, including the SparkNotes character summary and Wherever I Look, confirm Jeremiah’s bisexuality is part of the book canon.
- The Bisexual Resource Center lists Jeremiah Fisher as a bi character.
How does the show handle Jeremiah’s sexuality?
- The TV series has not explicitly addressed Jeremiah’s sexuality through Season 2.
- According to the Wherever I Look guide, the show includes other queer characters — notably Skye (non-binary) and Redbird (queer man) — but Jeremiah’s orientation remains implied rather than stated.
Season 3 may resolve the question: if the show stays faithful to the books, Jeremiah’s bisexuality could become explicit. If it diverges, the character’s identity may remain in subtext, creating ongoing discussion among fans.
Bottom line: Actor Gavin Casalegno portrays a character canonically bisexual in Jenny Han’s novels, but the TV series has not yet confirmed this on screen. Book readers know Jeremiah’s orientation; show-only viewers are still waiting for clarity — a gap the show must address.
The implication: How the series handles this in Season 3 will define the character’s legacy for a new audience.
Who does Jeremiah end up with?
The love triangle at the heart of The Summer I Turned Pretty has a definitive answer in the source material — but the show may change it. Here’s what the books tell us and where the series stands.
Does Belly lose her virginity to Conrad or Jeremiah?
- In the novels, SparkNotes character summary confirms that Belly’s virginity loss scene occurs with Conrad.
- This is a key plot point that separates the two romantic arcs in the book series.
Why does Belly not marry Jeremiah?
- In the third book, We’ll Always Have Summer, Belly chooses Conrad. The Wikipedia series entry notes that the trilogy ends with Belly married to Conrad.
- Jeremiah and Belly date during the series, but the relationship does not last — partly due to lingering feelings for Conrad and the emotional aftermath of Susannah’s death.
What is the age gap between Belly and Jeremiah?
- The age gap between Belly and Jeremiah is approximately one year. Belly turns 16 during the first book, and Jeremiah is 16–17 throughout the series.
- The Wherever I Look character guide describes Belly as 15 at the start, turning 16 during the summer narrative.
The show has already made changes from the books — including aging up characters and introducing new plotlines. Season 3 could break from the book ending entirely, leaving Jeremiah’s romantic fate in question for live-action viewers.
The pattern: Book canon favors Conrad, but the series has room to rewrite the ending.
What is Jeremiah’s real age?
Age is a tricky point for Jeremiah Fisher because the books and the show operate on different timelines. The difference matters for understanding why the character feels younger — or older — depending on the medium.
How old is Jeremiah in the books vs. the show?
- In the books, Jeremiah is 16–17 years old. The SparkNotes character summary places him alongside Conrad as a high school-aged character.
- In the TV series, the cast is aged up slightly. Jeremiah is portrayed as 17–18, consistent with the show’s older-teen casting decisions.
- The Wherever I Look guide notes Belly starts at 15 and turns 16, which would place Jeremiah around 16–17 in that timeline.
What is Gavin Casalegno’s real age?
- Gavin Casalegno, the actor who plays Jeremiah, was born September 2, 1999. As of 2024, he is 25 years old.
- Casalegno is a Texas-born American actor also known for roles in The Wait (2013) and Nocturne (2020).
The implication: The age difference between the actor and the character creates a familiar casting gap for teen dramas.
Was Gavin Casalegno ever married?
Fans frequently ask about the personal lives of the cast — especially when a character feels as real as Jeremiah. Here’s what’s known about the actor behind the role.
What is Gavin Casalegno’s relationship status?
- Gavin Casalegno is not married as of 2025, based on public records and social media.
- He has kept personal relationships private, with no confirmed public partner.
- His Instagram bio — “your favorite golden retriever” — is a playful reference to his character’s personality, not a relationship status indicator.
Is Conrad dating in real life?
- Christopher Briney, who plays Conrad Fisher, is in a relationship but not married. Briney has shared occasional public glimpses of his relationship on social media.
- Neither Briney nor Casalegno has been married.
The takeaway: Fans should separate the actor’s private life from the character’s on-screen relationships.
What did Jeremiah suffer from?
Jeremiah’s struggles are mostly emotional — and they’re central to understanding why he acts the way he does. The character carries weight that the show sometimes portrays through subtle moments rather than direct storytelling.
- Jeremiah deals with his mother Susannah’s cancer diagnosis and eventual death. This is a major emotional arc across both the books and the TV series.
- He struggles with feeling overlooked compared to his brother Conrad. The SparkNotes character summary notes Jeremiah’s more outgoing personality contrasts with Conrad’s reserved nature, creating a dynamic where Jeremiah feels less seen.
- No major physical health condition is depicted for Jeremiah in the books or show.
“Jeremiah is the golden retriever energy.”
— Jenny Han, book tour Q&A (2022)
“your favorite golden retriever”
— Gavin Casalegno, Instagram bio
This framing from both author and actor captures the surface-level charm — but the deeper emotional stakes are what give the character weight. The Penguin New Zealand character guide describes Jeremiah as “the life of the party,” yet his role in the story is far from simple fun.
The implication: Jeremiah’s suffering is relational and grief-based, not physical — and that makes his vulnerability easier to miss on first watch. The show’s quietest moments of his are often the most revealing.
